Product details
Overview
DD250S65K3C1NPSA1 from Infineon Technologies is a highly insulated 6500 V, 250 A reverse-conducting diode module designed for medium-voltage inverter legs in traction and industrial drive systems. It features AlSiC baseplate, 10.4 kV AC insulation (60 s), CTI > 600, and operates from –55 °C to +125 °C storage temperature.
For engineers reviewing the DD250S65K3C1NPSA1 datasheet, DD250S65K3C1NPSA1 pinout, DD250S65K3C1NPSA1 application, or DD250S65K3C1NPSA1 equivalent, key selection criteria include repetitive peak reverse voltage (6500 V), I²t rating (52 kA²s), thermal resistance (RthJC = 55.8 K/kW), and creepage distance (64.0 mm terminal-to-heatsink).
Technical Context
This module integrates a high-voltage silicon diode optimized for reverse-conduction operation in series with IGBTs in neutral-point-clamped (NPC) and three-level topologies. Its design supports fast recovery (tonmin = 10 µs), low forward voltage (VF = 3.50 V typ. at 250 A, 25 °C), and robust SOA up to 500 A peak reverse current.
Insulation architecture uses AlN ceramic as internal basic insulation (IEC 61140 Class 1), with AlSiC baseplate enabling enhanced thermal cycling capability. Creepage (64.0 mm) and clearance (40.0 mm) distances meet stringent medium-voltage safety requirements for traction-grade equipment.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage diode module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DD250S65K4 | Same 6500 V/250 A rating but uses newer Si diode chip with lower VF (3.25 V typ.) and reduced Erec (850 mJ max at 125 °C). | Optimized for higher efficiency in 10–15 kHz PWM drives; slightly reduced I²t (48 kA²s) limits short-circuit tolerance. | Select when system prioritizes conduction loss reduction over fault ride-through margin. |
| DD400S65K3 | Higher current rating (400 A nominal), same 6500 V, larger footprint (160 × 120 mm), RthJC = 42.5 K/kW. | Suitable for 3–5 MW applications; requires redesigned heatsink and busbar layout; not drop-in compatible. | Select only when upgrading power level and redesigning mechanical layout is feasible. |
Compared with DD250S65K4 and DD400S65K3, DD250S65K3C1NPSA1 offers optimal balance of fault robustness (52 kA²s), thermal cycling endurance (AlSiC), and compact size-making it preferred for space-constrained traction inverters where reliability outweighs marginal efficiency gains.

FAQ
What is the maximum allowable case temperature during continuous operation?
The module supports continuous operation with case temperature (Tc) up to 125 °C, as validated by thermal testing per IEC 60068. Junction temperature must remain ≤125 °C under rated current; derating is required above 100 °C case temperature per the transient thermal impedance curve in Figure 5 of the datasheet.
Can DD250S65K3C1NPSA1 be used in parallel configurations?
Parallel operation is not recommended without individual gate/diode current balancing networks. The module lacks integrated current-sharing features, and parameter spread (e.g., VF tolerance ±0.5 V) may cause uneven static current distribution. Infineon advises single-module per leg unless validated with external ballasting resistors and matched thermal mounting.
Does this module require forced cooling?
Yes. Continuous 250 A operation requires forced air or liquid cooling to maintain case temperature ≤125 °C. Natural convection is insufficient; thermal resistance from junction to heatsink (RthCH = 42.0 K/kW) mandates heatsink thermal resistance ≤0.25 K/W for 1000 kW dissipation scenarios.
What is the meaning of "C1NPSA1" in the full part number?
"C1NPSA1" denotes Infineon's internal variant code: C1 = standard isolation grade, N = Ni-plated terminals, P = press-fit baseplate option, SA1 = specific qualification revision per IEC 60747-9 for high-voltage modules. It does not indicate packaging format or RoHS status.
